Pipeline structure and pool body

Abstract

Disclosed in the present invention is a pipeline structure of a pool body. The pool body comprises a hard pool body accommodation cavity and a soft pool body accommodated in the hard pool body accommodation cavity, and an annular cavity is formed between the soft pool body and the hard pool body accommodation cavity; and the pipeline structure comprises pipeline branch pipes, wherein at least some of the pipeline branch pipes are accommodated in the annular cavity, and the pipeline branch pipes comprise a plurality of multi-way hard pipes and hoses, adjacent multi-way hard pipes being connected by means of the hoses, and a plurality of nozzles being provided on the multi-way hard pipes. The pipeline structure of the present invention does not abut against an outer side of the pool body and cause the pool body to bulge. Further disclosed in the present invention is a pool body.

1 . A pipeline structure of a pool body, characterized in that the pool body comprises a hard pool body accommodation cavity and a soft pool body accommodated in the hard pool body accommodation cavity, and an annular cavity is formed between the soft pool body and the hard pool body accommodation cavity; and
 the pipeline structure comprises pipeline branch pipes, wherein at least some of the pipeline branch pipes are accommodated in the annular cavity, and the pipeline branch pipes comprise a plurality of multi-way hard pipes and hoses, the adjacent multi-way hard pipes being connected by means of the hoses, and a plurality of nozzles being provided on the multi-way hard pipes.   
     
     
         2 . The pipeline structure according to  claim 1 , characterized in that the multi-way hard pipe is a four-way hard pipe. 
     
     
         3 . The pipeline structure according to  claim 2 , characterized in that two nozzles are provided on each four-way hard pipe. 
     
     
         4 . The pipeline structure according to  claim 1 , characterized in that the pipeline branch pipe is a water inlet branch pipe. 
     
     
         5 . The pipeline structure according to  claim 1 , characterized in that an end of the hard pipe connected to the hose is provided with an external thread structure surrounding the hard pipe, the external thread structure is connected to the hard pipe through a limit stop, and the limit stop, the external thread structure and the hard pipe enclose an open-ended waterproof cavity; and
 an outer periphery of the hose is sleeved with a tapered press ring and a locking nut, the hose is inserted into the waterproof cavity, the locking nut is threadably connected with the external thread structure, in an insertion direction of the hose, the tapered press ring is located between an end of the external thread structure and the locking nut, and the tapered press ring clamps the hose with an end of the hard pipe in the insertion direction.   
     
     
         6 . The pipeline structure according to  claim 5 , characterized in that the end of the hard pipe is provided with a tapered surface, and the tapered press ring and the tapered surface clamping the hose in the insertion direction. 
     
     
         7 . The pipeline structure according to  claim 6 , characterized in that in a direction opposite to the insertion direction, the tapered surface protrudes from the external thread structure for the tapered press ring to sleeve. 
     
     
         8 . The pipeline structure according to  claim 5 , characterized in that the locking nut is capable of moving the tapered press ring in the insertion direction toward the hard pipe during threaded connection with the external thread structure so that the tapered press ring clamps the hose with the end of the hard pipe in the insertion direction. 
     
     
         9 . The pipeline structure according to  claim 8 , characterized in that after the locking nut is fully connected to the external threaded structure, the tapered press ring and the end of the hard pipe jointly clamp the hose. 
     
     
         10 . The pipeline structure according to  claim 1 , characterized in that the nozzle is connected to the multi-way hard pipe by the hose. 
     
     
         11 . The pipeline structure according to  claim 1 , characterized in that the hose is a TPU pipe or a silicone pipe. 
     
     
         12 . A pool body, characterized by comprising a hard pool body accommodation cavity and a soft pool body accommodated in the hard pool body accommodation cavity, and an annular cavity is formed between the soft pool body and the hard pool body accommodation cavity, at least a portion of the pipeline structure according to  claim 1  being disposed within the annular cavity.
